Orbital data in astronomical units abstracted from Norton's Star Atlas (17th edition). (Except Asteroid belt, which are nominal figures) The calculations in this document accept the following figures as absolute.
PLANET	PERIHELION	MEAN A.U.	APHELION
MERCURY	0.306	0.3870987	0.467
VENUS	0.718	0.7233322	0.728
EARTH	0.983	Unity	1.016
MARS	1.381	1.5236915	1.666
ASTEROIDS	Nominal 2.00	3p/4 A.U.	Nominal 3.00
JUPITER	4.951	5.2028039	5.455
SATURN	9.008	9.5388437	10.069
URANUS	18.275	19.181871	20.088
NEPTUNE	29.8	30.057924	30.316
PLUTO	29.58	39.439	49.19
